SPECIFICATION forming' part of Letters Patent No. 793,117, t ated June 2T, 1905.

Application filed March l2. 1904. Serial No. 197.3%.

Be it know'n that Yl', 'luouAs S.Yrrununnl-i, a citizen ot' the United States ot' America, and a resident ot' Jersey (lity, county oli I'Iudson. and State otl New Jersey, have invented certain new and uset'ul Improvements in Storage- Battery Jars, of which the following isa specilit-ation.

My invention relates to a storage-lattery jar, and is designed t'or the purpose ot' providing a ,jar which may be advantageously usedA on automobiles or other places where it is likely to be iolted and where the acid contained in the iar would probably be spilled unless earet'ul provision were mader against this result.

lxelerring to the drawing's, Figure l is a plan view ot' my battery-jar; Fig. 2, a vertical transverse section ot' the upper portion ot' tl 3 jar, and Fig. 3 a perspective view ot the plate-holder.

Referring' to Fig. 1, the jar is shown divided into two cells and having a cover bolted onto the top ot' the jar, covering both cells. rlhrough the cover protrude binding-postsand vents.

1 is the jar, having' a flange 2 surrounding its upper edge, which is perforated with holes to receive bolts.

3 is the cover, having holes similar to those in the flange L), through which the bolts pass.

-t is the sott-rubber sheet which forms a gasket t'or the lid and is ot' the same size as the cover. The upper edge ot' the jar is tlat upon its inner surtace and beveled trom the llat portion outward to the outer edge, leaving a horizontal portion 5, which localixes the pressure ot the cover upon the sollt-rubber gasket t and serves to t'orm a tight joint between the cover and the jar.

t3 and 7 are positive and negative batteryplates.

8 is the yoke by which the positive plate; are connected to their binding-post.

t) is the yoke by which the negative plates are connected to their binding-post.

lt) is the binding-post ot' the positive plates, and llthe binding-post ot'thc negative plates.

It will be noticed that the yoke shown in perspective in Fig. 3, at'ter having been secured by soldering to the plates and having its arm extending inward, is bent upward and outward until the binding-post 1U, which is soldered into its end` is vertical :rnd may be passed through a suitabl apert m'e in the cover 3. Surrounding the binding-post lll is an annular recess and annuiar llange 1'2. In the arrangement ot the, battery-plates in the jar it is designed that the upper surlace ol the annular llange lL shall stand a little above the level of the top olA the jar, so that when the sott-rubber g'asket is pressed down upon the llange by the cover an acid-tight ioint will be lormed around the binding-post lt). This joint will be reint'orced when the nut l?) ot the binding-post is screwed home. 'l`he lot-ation ol" the yoke-arms projecting inward and then turned outward will have the ell'ect ot steadying the plates in the cell and preventing them lrom tiltingout ol place. The bend ol the arln will also have the ell`ect ot' permitting the end ol thel arm carrying the bindingpost to be bent laterally, so as to permit itto register with the hole provided t'or it in the cover ot the liar.

In the center ot' the cover is a gas-vent 1t. Thisgas-ventconsists ol a cylinder `15, screwed into the center ot' the cover, upon the top of which is screwed a cap It, having within ita gasket 1T, which rests upon the top olI the. cylinder l5. 1S is the gas-vent in the center ol the cap. From the umler side ol the cap at its center depends a portion oi diameter less than that ol the sleeve, through which there are lateral and vertical channels. The vertical channel deseends l'rom the top until itintercepts the lateral channels and there stops, so that there are only lateral openings into the. jar.

In operation the gas-vent 1H will prevent any acid l'rom escaping' l'rom the jar. rlhe acid as it is splashed bythe motion ol the vehicle up onto the sides ot the head will llow back into the iar, and it will be quite impossible t'or any portion otl the acid to escape trom the jar.

llaving thus described my invention, what I claim, and desire to secure b v Letters Patent, is

l. In a battery-iai'. the combination with a TOO jar and cover, two sets of plates forming a plurality ot sets of electrodes within the jar, each set ot' plates secured to a suitable yoke, the yoke having an arrn which extends inward and is then bent upward and outward, and a binding-post on the end of the arrn adapted to pass through the cover.

2. ln a battery-jar, the combination with a jar and cover, two sets of plates forming a plurality of sets of electrodes within the jar, a yoke for each set of plates provided with openings, extensions on each plate adapted to enter openings to secure each plate to its yoke, each yoke having an arm which extends inward and is then bent upward and outward, and a binding-post on the end of the arm adapted to pass through the cover.

3. In abattery-jar, the combination of a jar and cover, the cover being provided with a gas-vent which consists of a sleeve screwed into an aperture in the cover and closed by a cap Jfrom which there is a pendent portion of smaller diameter than the inside diameter of the sleeve, the pendent portion having vcrtical and lateral passage-ways which intercept each other, the lateral passagewvays opening into the space between the pendent portion and the sleeve and the vertical passage-way extending from the lateral passage-Way to the air, whereby there are only lateral openings into the jar.

4. In a battery-jar, the combination of ajar and cover` a soft-rubber sheet interposed between the jar and cover, a plurality of sets of electrodes forming two sets of plates within the jar, each set of plates secured to a suitable yoke to which is secured a binding-post and having an annular ange and recess on the yoke surrounding the binding-post, which is adapted to be seated in the soft-rubber sheet when the binding-post is passed through the rubber sheet and cover, substantially as described.
